Recap

The episode begins with Karen meeting Derek as she received his call. Derek tells Karen that he feels she makes a pretty Marilyn. He further tells her that he sees her as Marilyn in his head. Ivy just then comes in and sees the two of them together at a distance; Ellis too overhears the whole conversation. Later Rebecca comes in unnoticed. She tells Derek that she has a great idea about one of the songs which she needs to talk to Julia about. Tom is visibly exasperated to hear this. Rebecca meanwhile wants to focus on some other song. Karen later tells the guys in the troupe that she likes Rebecca, and admires the fact that she is very direct. They all then run into Rebecca on the street. Rebecca asks a pleasantly surprised Karen if she wants to go out in the night. ..
